Bassa Mawem was #2 in Speed but ranked #1 among the Combined participants. Although he was among the 20 % last in both Lead and Boulder he was #13 overall. In other words, you do not have to perform on a high standard in all three discipline. What counts is to be good in one. Another example of this is Marcin Dzienski who was second last, out of 87, in both Lead and Boulder but as he was #2 in Speed he was #22 overall. If he instead would have won in Speed who would have replaced Bassa as #13 overall.

The example from the female showing that multiplication creates unfair and strange results is Alexandra Rudzinskis #10 overall after 65 * 58 * 1, out of 68. As it stands, she can actually move up to #8 position with bad results in bouldering for her opponents. Interim results

Why do you think this is strange? We have discussed this in the past and it's known fact that if you are good at one discipline (1st, 2nd) and bad (last) at the other then your overall rank is better if you use multiplication of ranks instead of addition. E.g. if there are only 2 disciplines and only 20 (Olympic) competitors per each you can see below when your overall ranking is better (green), worse (red) or identical (white) when you use multiplication instead of addition:
Nevertheless, with three disciplines it's quite sure no speed specialist will progress to Sunday's combined finals, but it's quite possible speed will decide the winner between non-speed specialists.

Normally in "Combined" events it is about being good in all disciplines if you want to win or be high ranked. In the IFSC Combined you can practically skip Speed and nevertheless win and on the other side, you can get a good result if you are good in just Speed.

This means also that during 2019, we could see big federations like Italy, France and Russia influence the result just by a tactical maneuvers. It is just to let the speed climbers participate in two Lead and one Boulder event or vice versa. Before the last event, they can simply decide whether that Speed specialist should be allowed to participate in one more in order to also be included overall.
